    Hey guys i have a 225 V6 and i have replaced, points and condenser (purchased the points and condenser package where all you do is bolt it all on) and the coil. I have power at the coil and power at the points but i am not getting any fire at the plugs. The only things i have not replaced are the ballast resistor and the Dist. Cap. I figure since i am getting power to the coil the resistor is good. Could it be a problem with the cap? I have never had her running could it be possible that the PO had a wrong cap on it all together? I am outa ideas

    You need to start at the coil and work from there, you didn't mention these two things:

    Spark from the coil wire to the cap?

    Spark across the points?

    Is power getting from the coil to the points or is it grounding out somewhere on the distributor body?

    Whats the best way to check from coil to Distributor? my meter is out on loan right now, just trying to think about how to check it without getting a nice little jolt

    Are you getting spark across the points? That would check that but without a meter no way to be sure it's that wire or the points installation.

    Just a place to start looking for something wrong.

    I just checked the Coil wire and it is good, turned it over and watched the points they are clicking away like they are supposed to, The point and condenser setup came as one unit and i just bolted it on and attached the (-) wire from the coil to the points. With my test light i have power at the points so i am at a loss.
    Could it be a timing issue? I pulled the distributor to check out the gear but i marked it and when i put it back in i made sure #1 was up and when i put the rotor button on it was pointing at number one. Even with a odd fire it should still be this way right? But that still would not explain no spark. I said i would not get frustrated working on this thing since it was just for fun, but i lied i guess. I cant really tell visually if i am getting a spark across the points, should it be easy to see? If it is then i would assume there is no spark.

    maybe I missed it but you did bump the points up to a lobe and set the gap correctly?

    the whole reason i got the points condenser package is that it does not need to be set. t all looks correct will have to dig out my feeler gauge and see what its at, but i should be around 17 or so right?

    someone that owns an odd fire can chime in w/ the gap, but that's the first
    thing I'd check. IIRC there's tune up specs in the tech section you mat find your answers there

    The points still need to be set regardless whether they are integrated with the condenser or not. I'd start there..... Nickmil

    Please give us some pics with the points mounted in the distributer.:coffee:

    Are you getting a spark from the coil wire when the motor turns over?

    When you pulled the distributer, did you rotate the crank at all, with the distributer out?

    If you get a spark from the coil center wire when engaging the starter with the key, then the fault will be at the cap, or the rotor. With those points shown, the cap should have a little window that lines up with the allen socket of the points. 17 is a good starting gap, it should fire with that.

    That uniset points is a good set-up. I have it in mine. As you have found out, there is not enough room to install feeler gauge. Too compact. Here's what you do. click engine around until you are coming up to a lobe and then you twist top of dist plate holding mechanical weights while watching your points. they should open slightly and be sure they close as it moves down from lobe. If that is OK then take your coil wire and poke it into a spark plug and ground plug. See if plug sparks. Try that. You will have to set dewll at 32 deg after you get er running.

    Some one correct me if I'm wrong, but you should be able to set the dwell with the cap off if a friend or spouse will operate the key for you. Doesn't take much to set it.:coffee:

    Come to think of it, don't see why not. But you have to be very careful and keep outa that fan or temporarily take off belt.
